Y Y:een-srnrncennrivronorner MEMBER.

` Application led December 20, 1915.

To all whom z't may concern.'

Beit known that I, J oHN I-IMoNTs'rnnAM, a citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Bed- Spring-Iieinforcing Members, of which the following is a specication. p

This invention relates to bed-spring reinforcing-members, the objectof the invention being to provide a simple varticle of this character by which transverse sagging of a bed-spring is elfectually prevented, without affecting the proper longitudinal resiliency of the spring and without interfering with the comfort of the occupant of the bed.

In the drawings accompanying and form-V ing part of the present specification I have illustrated in detail one form of embodiment of the invention which I will fully set forth I do not restrict myself to this showing; I may depart therefrom in several respects within the scope of the invention dened by the claims following said description.

Referring to said drawings:

Figure l is a perspective View of a bedspring furnished with a reinforcing-mela ber comprising the invention;

Fig. 2 is a top plan view of said reinforcing member.

Fig. 3 is a sectional detail showing one of the hooks in its two positions by full and dotted lines respectively, a portion of the spring also appearing.

Fig. 4 is a detail view in perspective of one corner of the member, and

Fig. 5 is a transverse sectional view of the device. y v

Like characters refer to like parts throughout the several views, which are on different scales. p

The bed-spring reinforcing-member is preferably placed on top of the spring, and while advantageously it is removable, it need'not always be so in all cases. As represented it has means by which it can be detachably connected with the spring, so that it may when desired be taken from operative relation. While upon the spring said member supports the mattress, extending crosswise of the spring for practically the complete width thereof. It does not extend, however, the complete length of the spring but is disposed nearly midway thereof, being a trifle nearer the head. than the foot Speccaton of Letters Patent.

of the spring in which position it is adapted best to resist the weights or stresses applied to the spring. rEhe member possesses a certain amount of stiffness or rigidity' transversely of the bed-spring, not an ab normal amount for the device has a certain degree of resiliency laterally or transversely of the bed, enough preferably to insure it being comfortable yet still sui'licient to prevent transverse dents or hollows being made in the spring. Said member is flexible longitudinally of the spring, and this flexibility is comparatively and in fact quite free to permit easy and natural longitudinal bending of the spring. As I have noted I do not restrict myself to any particular construction by which I can secure the prime advantages set forth. In the drawings I have shown'an organization which is highly advantageous and which involves the invention. This I will describe in detail to comply with the statute and enable those skilled in the art to practice the invention.

In F ig. l the numeral 2 denotes a bed bottom equipped with the spring 3, the latter being partly illustrated in Fig. 3. rlhe reinforcing-member is denoted in a general way byl and it has bars 5 of which there may be any desired number, the length of eachpreferably virtually agreeing with the width of the spring 3. These crossbars are somewhat' longitudinally resilient and are spaced apart which permits flexibility and ventilation; they may be made of any suitable material. Wood answers satisfactorily in this connection o1 sheet metal might be provided. llhile said cross bars individually possess a certain amount of longitudi nal resiliency, they in the aggregate or collectively resist stresses applied to the spring.

In the present case this relative rigidity or stiffness of the reinforcing member longitudinally thereof or transversely of the bed spring, is secured by the comparatively close arrangement of the bars or strips 5. Said cross bars are flexibly connected together for instance by the rods 6 of which there may as shown be two, the bars being perforated near their opposite ends for the comparatively free passage of the rods 6. The terminals of the rod 6 are threadedto receive the nuts 7, constituting suitable end stops, washers as 8 being interposed between -the nuts 7 and the adjacent cross bars 5.

The nuts present a convenient means for holding the parts of the reinforcing mem ber in assembled` relation. Between the two central bars 5 I may as represented, dispose coiled springs 9 whichy encircle the` rods 6 between said central cross bars, the springs bearing at their ends against said central cross bars or against washers as l0. Sur

roundingftherods 6 between the othericross;` bars are spacing members or tubes as. l1.

bearing at their ends against' washers as 12 fitted against adjacent faces of the cross bars. These spacing members ll' as willy be clear separate the cross bars other than the.

two v central ones, the necessary distance, while the springs 9 actingy against opposite. faces of the central cross bars force the two groups of cross bars outwardly firmly and substantially against the holding nutsJ 7L rIher rods 6 may be of wire of`a size sufficient.

to insure proper bending between the cross bars,.for example wire of approximately one From this it will be clear that the latches.

can be swungup or down. In. F ig. 3 I

have shown one of'the latches 13' in its two positions by full andi dotted lines respectively. When the latch is inthe full` line position and with the reinforcing member resting on the spring 3, the lower arm of the latch can. be hooked into the spring,

l Should the reinforcing, member be inverted' what is shown as the upper arm ofthe latch can be engaged between the coils of the spring as shown by dotted lines in saidl Fig. 3; The bar 5 adgacent each latch may if" desired be equipped with stops I4 in the form of pins to limit the motion of the latches.

will be understood, the reinforcing member is susceptible of advantageous association with either new or old bed' springs. When mounted upon a new spring it' materially prolongs the life thereof'by distributing the weight of the occupant oroocupants of the bed uniformly across the whole width,` tofsA the: springs, the2 consequence being that each coil and strand supports its proper extent: of the load. When mounted upon an old spring it has the effect of restoring andi preserving the same.

What I claim is:

.1'. A bed-spring reinforcing-member relatively rigid in a direction transversely of the4 spring andfflexible longitudinally of the spring andi providedy with` hook means. to engage.A into the fabric of the spring to hold, the.- member against movement bodily with, respect to the spring.

2. Abedlspring reinfbrcingfmember comn prising a plurality of'cross bars, iexible elements extending freely through thecross bars nearthe ends thereof, stops on the ends ofthe flexible elements, springs carried by the flexible elements and acting against intermediate cross. bars andl'tending to. const'antlyY force saidl intermediate cross bars outwardly,l and spacing, members carried. by the flexible elements between theother cross bars to positively separatesaidother cross bars from each. other.. p

4; A bed-spring reinforcingfmember comprising cross bars, wires extending through the cross bars, nuts threaded' on the ends of the wires and bearing against the outer sides of the end cross bars, Springs coiled about.
